Well I went back to the muffler shop and found out that I had an exhaust leak and that was some of the noise that I did not like but when they got it fixed it did sound better but it still did not sound good to me.
I had them cut off the tail pipes and put turndowns on it and all I can say is WOW!!!

This thing sounds mean. I take back every bad thing I ever said about the 1 chamber flows.
They are 3" 1 chamber flowmasters with 3" turndowns.
I will try to get some sound clips soon.
